Greentube Expands Portfolio With New Flaming Devil Slot Featuring Devil Collect

Greentube, part of the NOVOMATIC Digital Gaming and Entertainment division, released Flaming Devil™ on 18 August 2026. The new slot leverages familiar mechanics with the addition of innovative features designed to extend player engagement and diversify Greentube’s offering across regulated markets. The core feature, Devil Collect, activates on every spin, while a Free Games Wheel with stackable multipliers elevates bonus potential throughout the session.

Flaming Devil™ and the Devil Collect Feature

Flaming Devil™ is the latest addition from Greentube, developed in Vienna and launched as an expansion of the NOVOMATIC Digital Gaming and Entertainment portfolio. The title uses a classic ‘hell’ design, distinguished by 243 ways to win on every spin. Its central mechanic, the Devil Collect Feature, ensures that any Devil symbol landing on the reels automatically collects and awards every coin prize currently displayed.

The Devil Collect functionality is not restricted to bonus rounds. As Richard Ganster, Director of Games Strategy and Games Portfolio Management at Greentube, explained:

“The Devil Collect feature is active on every spin, not just during the bonus round, so there's always something to keep attention fixed.”

By rendering the collect function available throughout base and bonus play, Greentube intends to keep engagement steady and reward patterns consistent, aligning with preferences in regulated casino markets.

Free Games Wheel and Bonus Mechanics in Flaming Devil™

The bonus structure involves triggering the Free Games round by landing three or more Bonus symbols. Within Free Games mode, collecting four Devil symbols awards access to the Free Games Wheel. This interactive feature can grant:

• Additional Free Games
• An increase to the Free Games Multiplier

Any multiplier won applies to all subsequent Devil symbol wins for the remainder of the Free Games round, enhancing potential payouts. Crucially, the Free Games Wheel is not a one-off event—it may be activated multiple times in a single bonus session, incrementally extending both the round duration and the multiplier effect. This structure positions Flaming Devil™ as a title with significant bonus longevity and win variance.

Richard Ganster further commented:

“The Free Games Wheel is a key highlight. It can be awarded multiple times in the same round and the Free Games Multiplier can stack significantly, giving the title a strong ceiling on win potential while keeping the base action pace accessible.”

Addition to Greentube’s Regulated Market Portfolio

The Flaming Devil™ release continues Greentube’s recent strategy of pairing familiar slot themes with layered bonus mechanics. Officials at Greentube have positioned this approach as an answer to growing demand for titles that are both accessible and capable of providing extended engagement.

The use of an active collect mechanic and dynamic multipliers represents a step forward for the supplier’s roadmap. Flaming Devil™ will now be available to partners in relevant markets, expanding Greentube’s catalogue of games optimised for compliance and high retention.

Industry Context and Outlook

Greentube’s rollout of Flaming Devil™ fits into a broader trend among suppliers to supplement core portfolios with feature-driven content. As regulated markets increase expectations for unique in-game experiences and sustained player activity, slots utilising recurring bonus triggers and scalable payouts—like Devil Collect and the Free Games Wheel—are likely to become more prominent. The company’s strategy, blending reliability with incremental mechanical depth, aims to maintain appeal for operators seeking flexible content solutions across jurisdictions.
